I think the problem with Jet is not the current level of service, but the way it has come down over last couple of years. If I travel in economy in US or Europe, I align my expectations accordingly and know what is coming. but in case of Jet, I am (or was) used to getting pampered, which is no more the case. So it may really be a case of over-expectation by people like me. Having said that, I experienced relatively bad quality of service in last couple of my international business class travels. Just hope those were exceptions.
